LIQUID-FUEL BURNER.

To all whom it may concern:

Be it known that I, VVILLIAM R. MCHILL, a citizen of the United States, residing at Moran, in the county of Allen and State of Kansas, have invented a new and. useful Liquid-Fuel Burner, of which the following is a specification.

This invention relates to liquid fuel burners in which a gas or vapor is generated in a coil located above the burner proper, and it has for its object to provide a burner of this kind in which a more perfect combustion of the gas or vapor is effected, smoke and soot being eliminated.

Another object of the invention is to provide a burner which is especially adapted for crude oil, and which is so constructed that it may be readily applied to any ordinary cooking or heating stove, or furnace, without altering or modifying the structure thereof.

With these objects in View, the invention consists in a novel construction and arrangement of parts to be hereinafter described and claimed, reference being had to the accompanying drawings, in which,

Figure 1 is a vertical section of a fragment of a heating stove, showing the burner in position therein, the burner being shown in section. Fig. 2 is a horizontal section on the line 2-2 of Fig. 1. Fig. 3 is a horizontal section on the line 3-3 of Fig. 1.

In the drawings, 5 denotes the shell of an ordinary heating stove, in the fire pot of which the burner is placed. The grate will be removed, and a ring 6 substituted therefor, said ring being carried by the usual grate supporting lugs or flanges 7 of the stove. The ring supports the several parts constituting the burner.

Secured to the ring 6, and rising therefrom a suitable distance, are standards 8 carrying a coiled tube 9, said tube being rigidly secured to the standards by suitable clamps shown at 10. This coil serves as a retort, the upper end of the tubing being connected to an oil supply pipe 11 entering the stove at any suitable point, and connected to a tank or other source of supply, the tank being, preferably, elevated, so as to give a gravity feed.

To the lower end of the coiled tube is con nected an elbow 12 which carries a closed casing 13 into which the gas or vapor generated in the retort is discharged. The cas- Specification of Letters Patent. Patented N 22, 191() Application filed April 11, 1910.

ing is cylindrical in form, and has a conical top 14 at the apex of which is located a deflector plate 15 which is circular and has a greater diameter than the casing. The deflector plate is held in place between the apex of the top 14, and a shoulder 16 on the elbow 12, said elbow screwing into the top 1st. This arrangement affords simple and convenient means for connecting the casing and the deflector plate to the coil.

The bottom of the casing is closed by a plug 17 which screws thereinto, said plug, on the inside of the casing, being formed with a depression 18. On the bottom of the plug is a lug 19 from which extends a screw threaded stem 20. This stem carries a shallow pan or tray 21, the latter having an opening through which the stem passes. A nut 22 is screwed on the stem, the pan being located between the nut and the lug 19. The pan is thus supported by the casing 13 beneath the same. Near the top of the casing are outlet openings 23.

in operation, the oil is turned on, and allowed to run through the coil 9 into the casing 13 until it flows out of the same through the openings 23 into the pan 21. After a suilicient quantity of oil has run into the pan, the supply is shut off, and the oil in the pan is ignited. The flames from the burning oil quickly heat the coil, and before the oil burns entirely out, the supply is again turned on, and upon passing through the heated coil, is vaporized, and passes in this form into the casing 13, from which it issues through the openings 23, at which point the gas or vapor is ignited. -The flames from the burning gas or vapor are deflected laterally and spread out by the plate 15, and pass upwardly around the coils, so that the latter are kept hot and in proper condition to continue the vaporization of the oil flowing therethrough. The convolutions of the coil are arranged horizontally, and the casing 13 stands vertically below the coil in the center of the circle described thereby. The diameter of the plate 15 is less than the inside diameter of the coil, which permits the flames to pass within the coil, and thus play around all portions thereof. The burning gas or vapor is mixed with air, which produces perfect combustion, and smoke and soot are practically eliminated. The ring 6 encircles the casing 13 substantially midway between its a large flame being upper and lower ends, the internal diameter. of the ring being such as to permit a large volume of air to flow through the space be- "can'be' readily applied to any ordinary domestic cooking or heat-ing stove, or furnace. The severalparts constltuting the burner are c all supported bythe, ring 6, so that no fastening devices are'required, the ring belng merely olaced on the supporting lugs of the grate, after removing the latter. The burner makes a large hot fire equal to natural gas, and is economical in its consumption of fuel, produced'with a very small quantity of oil.

That is claimed is:

1. In a liquid fuel burner, a supporting ring, standards rising from the ring, a coiled tube supported by the standards, and a casing carried by the coil at its lower end and encircled by the ring in spaced relation therewith, into which casing the coil discharges,

said casing having outlet openings.

2. In a liquid fuel burner, a supporting ring, standards rising therefrom, a coiled tube supported on the standards, and a casing carried by the lower end of the coil into which casing the coil discharges,said casing being encircled by the ring in spaced relation therewith, and having outlet openings.

3. In a liquid fuel burner, a supporting ring, standards rislng from said ring, a colled tube supported on the standards, a

' casing carried by the lower end of the coil and encircled by the ring in spaced relation therewith, into which casing the coil discharges, said casing having outlet openings, and a deflector arranged above the casing between the same and the lower end of the coil.

l. In a liquid fuel burner, a supporting ring, standards rising from the ring, a coiled tube supported on the standards, a casing carried by the lower end of the coil, into which casing the coil discharges, said cas-- ing having outlet openings, and a pan located below the casin 5. In a liquid fuel burner, a supporting ring, standards rising from the ring, a coiled tube supported on the standards, a casing carried by the lower end of the coil, into which casing the coil discharges, said casing having outlet openings, a stem carried by the lower end of the casing, and a pan located beneath the casing, said pan being supported on the stem.

In testimony that I claim the foregoing as my own, I have heretoafiixed my signature in the presence of two witnesses.
